What is the difference between a somatic reflex and an autonomic reflex quizlet?
Somatic reflexes involve contraction of skeletal muscles. Autonomic reflexes regulate smooth muscle, cardiac muscle, and endocrine glands.
What determines if a reflex is autonomic or somatic quizlet?
If the reflex involves the contraction of skeletal muscle as the effector it is called a somatic reflex. If the reflex involves the contraction of smooth muscle, cardiac muscle or glands, it is called an autonomic (visceral) reflex.
What are somatic reflexes?
Somatic reflexes involve sensory neurons that connect sensory receptors to the CNS and motor neurons that project back out to the skeletal muscles. Visceral reflexes that involve the thoracolumbar or craniosacral systems share similar connections.
What is an example of a somatic reflex?
This occurs when a nerve pathway connects directly to the spinal cord. Examples of reflex actions include: Jerking your hand back after accidentally touching a hot pan. Involuntary jerking when your doctor taps on your knee.
What differentiates an autonomic reflex?
What differentiates an autonomic reflex from a somatic reflex? A key difference is that a visceral reflex arc has two neurons in its (autonomic) motor component, whereas the somatic reflex arc has a single (somatic) motor neuron.
What is a major difference between visceral and somatic reflex arcs?
The main difference between somatic and visceral reflex is that the somatic reflex occurs in skeletal muscles whereas, the visceral reflex occurs in soft tissue organs. Furthermore, the somatic nervous system produces somatic reflexes while autonomic nervous system produces visceral reflexes.
What do somatic reflexes activate?
Somatic reflexes involve specialized sensory receptors called proprioceptors that monitor the position of our limbs in space, body movement, and the amount of strain on our musculoskeletal system. The effectors involved in these reflexes are located within skeletal muscle.
What is the order of a somatic reflex?
Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc.
What is autonomic reflex?
Autonomic reflexes are unconscious motor reflexes relayed from the organs and glands to the CNS through visceral afferent signaling.
Are reflexes autonomic or somatic?
There are two types: autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles). Autonomic reflexes sometimes involve the spinal cord and some somatic reflexes are mediated more by the brain than the spinal cord.
Are reflexes somatic or autonomic?
The autonomic nervous system regulates organ systems through circuits that resemble the reflexes described in the somatic nervous system. The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction.
What are autonomic and somatic reflexes?
The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction. The autonomic system, however, targets cardiac and smooth muscle, as well as glandular tissue.
